Double MC connector

[Gategator37]

The attached website shows a double MC connector. Can only one side of this MC connector be used without plugging the other side? Or is that a code violation of NEC 314.17(A).

Thanks for everyone's help.

that would be a violation no different that an open KO in a box.
